Float height ... with pics

[Packman]

2004 300 ec float level , ok so ive got the carb apart to give it a clean out and ive noticed now and again when its on the side stand fuel is coming out of the over flow pipe ....

So the float was set high up so i looked at a few post here so ive reset the carb and taken a few pics so what do u guys think ...

if i'm not mistaken,there's a little spring in the float needle, so that might be faulty.
just helping you think, specialists will have to confirm that, or not

I wouldn't hold the carb so level,more of an angle .so the float valve is closed,but the spring isn't compressed. Use a measuring tool to verify height. 1mm can make a difference,in the carb performance.

as above , how did you get your carb so clean , you could almost swear it was brand new

Ultrasonic cleansed?

Like others have said. Lay the carb at a 45 degree angle instead of upside down. You just want the point that the needle valve engages. Then when you think its right flow test it on the bench with the bowl off and modulate the floats with your thumb.

Cant seem to find any diagrams or pics of were the float should be or how it should be measured ?

Yes its clean a toothbrush and carb cleaner and airline ....

AS1 = 18mm std
AS2 = 6.5mm std.

Most will increase that by a mm or so (lowers fuel level to avoid splashover due to forward angle of carb). As per image, take that measurement with the carb at 45 degrees. If its fully upside down it depresses the float needle which skews the measurement. You want it just resting against the needle.

To confirm, all Keihin measurements should be done when the needle has seated but not compressing the needle spring.

Thats affirmative

Well i did this to the book and guess what yep it flowed out the over flow more than ever haha , turned the carb found removed the float and around 1mm of adjustment and she seem sweet. After turning the reads around and adding the 42 pilot jet she is ticking over very nicely.

Will run it up and down the road monday to make sure its ok .....
